If you didn't romance Solas you get the Tower. If you did romance him you get the Hierophant card AFTER he dumps you and it remains after the game finishes.
This is what keeps me spiraling about his plot.
I, for one, am with you. The card change/romance lock after the break up gives me hope. Straight-up hope. I don't see any reason not to be optimistic.
Solas wasn't always going to be a romance option, therefore all future content is going to suck? He wasn't going to be a romance and all content up to this point has been amazing.
He's got plans that are going to be carried out no matter what? All the more reason to concentrate on his feelings and what is going on in his head--which is a whole freaking lot of love.
The break up scene is, imo, the best romantic scene I've ever seen. I don't think love has ever come through as well as it did while he was breaking up with her. I love that scene. I replay it as often as I replay the ridiculously well done kissing scenes--and I replay them a lot.
This romance is so well done. Why would that suddenly change?
